XJ750 Seca and XJ750 Euro MODELS FORK TUBE PARTS:
NOTE: items marked below in red are the parts typically needed when doing a basic fork system rebuild.
A good visual review of the procedures needed for rebuilding the 1981-83 forks can be seen at:

And here's the secrets to that funny and unique "oil lock valve assembly" used only on these models, and the proper orientation of all of those special washers:

Owners of the 1984 XJ750RL models should follow the XJ900 rebuild procedures:

and

All XJ750 Seca owners should also wish to note the procedure needed to separate the inner tubes from the lower tubes (the "battering ram" procedure) since these forks also use the slider bushings on the bottom of the chrome tubes as shown on these XJ900 forks:

FORK TUBE REBUILD KITS:
We now offer both a BASIC FORK REBUILD KIT and PERFORMANCE FOR TUBE REBUILD KITS so that you can get all the typically-needed rebuild parts under one simple part number. Each kit is specifically assembled and correct for your particular model bike. NOTE: fork rebuild kits do not include any of the items used in rebuilding the anti-dive units; a separate kit to rebuild those is available as part HCP22001 and is listed in the anti-dive parts section further below.
- NOTE: the lower tube “dust boots” (sometimes called dust seals) are not included in the basic fork tube rebuild kits, but are available separate and can be found further below.
Basic fork rebuild kit contains at least the following items:
- cap bolt o-rings.
- cap bolt retaining rings.
- standard quality lower fork tube oil seals.
- oil seal retaining clips.
- oil drain screws and gaskets.
- damper rod head piston rings.
- damper rod bolts and crush washers.
- air joint o-rings, cushions, and retainer rings (all except 1984 XJ750RL kits).
- air valve o-rings and valve cores (all except 1984 XJ750RL kits).

Inner Tube Gaiter Boots:
Although not originally used on any XJ-series bikes, these accordion-pleated thick rubber boots fit into the area between the bottom of the steering underbracket and the top of the lower (outer) fork boots, covering and protecting this area from damage, while providing an "old-school" or cafe-racer type look. They are retained to the chrome tube itself (at their top end) via spring clips, and to the top of the lower fork tube via metal screw-clamps.

$ 14.95
NOTE: gaiter boots normally do not require any type of retainer at their upper end, as the tight friction fit between the boot opening and the chrome tube prevents migration of the boot. If movement seems to occur, then we recommend the use of thin, black electrical wire ties to cinch the boot flange tightly to the tube.

Inner Tube Fork Springs:
HCP9438 Aftermarket front suspension COIL SPRINGS, one pair does both forks. For all 1981-83 XJ750 Seca and XJ750 Euro models. Front spring spacers are required to be used with these springs and a pair of "thick-wall PVC pipe" spacers are included and you can use them instead of the HCP8284 spacer tube and the HCP8239 spring seats. These plastic spacers will still need to be cut to length. Optionally, you could use a pair of the HCP8239 spring seats (one for each spring) and the fabrication of a 42.80mm long spacer when replacing stock springs…..or you can order the HCP21024 spacers tubes which are already cut to the correct length. Optionally, you can use the HCP8284 spring spacer tube (stock for 1982-83 XJ650 Maxim models) and cut it down to the proper length; one tube will provide enough material to do both springs and fork tubes). NOTE: due to the difference in size of this spring versus stock springs, you will need to use approximately 12 cc's less fork oil (for a total of 297cc's per tube) when installing these springs and using the stock thin-wall metal spacer tubes as recommended above. The use of other type of spacers (thick-wall PVC pipe, for instance) will change this recommended fork oil volume by an unknown amount. NOTE: springs should be installed with the tighter (more-closely spaced together) coils towards the top of the fork tube.

Steering Stabilizer and Hardware:
HCP4543 OEM rotary steering stabilization DAMPER UNIT. Fitted only to 1983 XJ750 Seca models, this round “shimmy-eliminator” unit is fitted to the underside of the lower steering bracket, and interacts against the forward “finger” of the oil cooler mounting loop bracket which is welded to the front frame gusset……and thus provides a resistance, stiffening, and counteraction to fork movement. Mounts simply via a splined shaft and a retention bolt. NOTE: will not fit 1981-82 models, as they do not have the splined shaft receiver nor have proper locating tab or clearance for this device. Although these units are brand new, they should be filled with the proper viscosity of oil and all of the air should be bled out of them (using the two “center” screws). The recommended fluid to use is 15W or 20W fork oil, although you could use a thinner or thicker weight oil is desired…….just like with the forks themselves, the higher the viscosity, the more “dampening” (or resistance to rotary movement) you will obtain. NOTE: 1983 models could have been fitted with this rotary damper unit pr a more traditional fork-tube mounted “piston” style steering stabilizer. The piston stabilizer is normally seen only on bikes with the larger front fairing (“touring package” option).

$ 17.95
Oil Seals:
NOTE: when installing oil seals, make sure that the area where the seal will fit into is clean, free of any nicks and burrs, and that the lower tube metal slide bushing is fully seated. Oil seals install with the large opening facing down, into the tube, and on most seals, the small cast lettering and numbering on the seal faces upwards.
Seals are designed to be installed with a seal driver of some type, although a properly sized piece of hard plastic tubing, perhaps with a proper sized metal washer on top of the seal to "spread the load", works as well. Always make sure that oil seals are fully seated and not damaged or installed in a crooked or cocked manner.
NOTE: all of the following oil seals are 11mm tall, and their use eliminates the need for both the upper (HCP12948) and the lower (HCP3092) spacer washers as originally used on these models. The original oil seals were 7mm tall, and this required the use of the spacer washers to “shim-up” the original seal to the proper height.

Lower Tube Anti-Dive Unit Parts:
The front fork ANTI-DIVE SYSTEM on these models are almost always in need of a complete, thorough cleaning and rebuild. While many people claim that the anti-dive system is a "useless" feature, the real reason may be that the system is so internally fouled and seized that it simply is not operating, at all!
Anti-dive control units are divided into an "upper" (or "top") section, which is the brake plunger assembly....this upper section is where the brake hose, from the brake caliper, attaches. The brake fluid BLEEDER SCREW and the fluid DRAIN SCREW are located in this upper section, as well as the brake plunger piston unit. The O-RING on the plunger should be replaced during a rebuild procedure, as well as a thorough cleaning and polishing of the piston bore. Additionally, there is a snap-ring that retains the damper plunger piston unit into the housing which should be replaced if it is rusty o deformed. HINT: if this piston unit is seized, the use of the HCP12230 Piston Popper fitting will easily free it up.
The "lower" (or "main") section of the anti-dive unit is the larger damper piston assembly (which is bolted to the fork tube), and which contains the damper piston spring and piston. Under hard braking, the brake fluid pressure forces the brake plunger (in the top "brake plunger assembly" section) to push down on the damper piston and its spring, restricting the flow of fork oil in the fork tubes, thus "stiffening" the fork system temporarily----and reducing the amount of front end "dive" during hard braking. The O-RING on the plunger should be replaced during a rebuild procedure, as well as a thorough cleaning and polishing of the piston bore. And the housing-to-fork tube O-RINGS should also be renewed. The small fluid DRAIN SCREW and it COPPER GASKET is typically replaced, and finally, the lower spring seat O-RING at the very bottom of the lower housing, should be replaced to prevent any leaks.

NOTE: if you want to disable your anti-dive system, you will need to remove the hose from the caliper to the anti-dive unit (and replace the caliper end double-depth union bolt with the single-depth union bolt used at the anti-dive unit end of the hose) and block-off the anti-dive fluid port with this plug:
HCP12991 Aftermarket brake system fluid port BLOCK-OFF PLUG, correct size hex-drive set-screw is used to replace a brake hose union bolt when not in use. Use 1 per anti-dive unit.

NOTE: speed-bleeders should NEVER be used when first re-filling a "dry" brake system----one where the lines, calipers, or master cylinder has been rebuilt or changed, for example----as the air in the system will compress, and the speed-bleeder valve will prevent fluid from flowing through the system. Always bleed dry systems using standard bleeder screws first, and only then install the speed-bleeders, and re-bleed!

w) Lower Fork Tube DAMPER ROD RETAINING TOOL. This long aluminum tool, with proper sized nuts on each end, is used to retain the top of the fork damper rod (in the bottom of the chrome tube) when removing or installing the damper rod retaining screw. One end has a 19mm hex and the other end has a 22mm hex, so it will fit all styles of XJ-series bikes except XJ600 Seca II, 1981-83 XJ750 Seca, XJ1100, and all XS1100 Special and Midnight Special models. This tool will make the disassembly of your upper tube from the lower tube much easier! NOTE: this tool is available for short term rental, please see the “rental” section within the THE TOOLBOX section of our catalog at:
http://xjbikes.com/forums/index.php?threads/xj-parts-catalog-section-p-the-toolbox.44630
and review the availability and procedures in the TOOL RENTAL section.
NOTE: the HCP4402 tool does not work with certain forks (the XJ750 Seca being one of them) since the head of the damper rod does not have the internal fluting which the damper rod tool would catch onto (thus locking the damper rod in place, allowing the bolt to be removed). Instead, the damper rod is held via the insertion of a thin, round object (allen wrench of a phillips-drive screwdriver shaft) thru the lower hole in the lower fork tube where the anti-dive housings attach to the lower fork tube. This tool will go thru a drilled hole in the damper rod, thus locking it in place (preventing rotation).
You can see a good image of this about half-way down the page (during the re-assembly process, although, it will probably also be necessary during the dis-assembly process) on the following page:

Super-Penetrant Fluids and Lubricants:
Sometimes, the toughest part of working on a vehicle is battling the effects of time: seized fasteners, caused by rust, corrosion, and other factors, turns what should be a 5-minute effort into a 50-minute (or more) chore, complete with rounded-off, ruined, or snapped fasteners, e-z outs, heli-coil inserts, and more.........and that's just not right.
While the proper use of our various Anti-Seize products will prevent these nightmares from occurring in the future, you're stuck in the here-and-now, and the best way to handle these obstacles is to have the proper tools at the stand-by; and in the case of fastener seizure, the proper "tool" is a can or two of our SUPER PENETRATING LUBRICANTS at the ready; a couple of squirts, a little bit of time-----perhaps some heat for those really nasty situations----and you're on your way again, hopefully not too much worse for the experience.....
Great for use on all fasteners, fork tube cap bolts, intake and exhaust manifolds bolts, studs, and nuts, lock cylinder tumblers, or anywhere an un-cooperative fastener can be found. Can even be used to help un-seize frozen engines!
Be aware that these products are not your typical, garden-variety, run-of-the-mill "retail" type products; these are designed an used as industrial- and military-strength products, meaning they have special formulations that include a dollop more of the "good stuff" within them to solve the toughest seizure problems imaginable (the "good stuff" ingredients cost more, and it is those compounds that are left out of or reduced in concentration in "retail" level consumer products).
NOTE: the following product(s) can only be shipped via ground transport (which thus eliminates the postal Priority Mail, postal Express Mail, or private carrier Expedited levels of service for this item) and cannot (and will not----don't even ask!) be shipped outside of the continental USA. Additionally, there may be a per-package weight or quantity restriction, and thus multiple-unit orders of this product may have to be shipped in separate packages and will incur additional shipping charges.
HCP10331 Aftermarket standard-duty PENETRATING LUBRICANT, in a generous 16-ounce aerosol can. Oil-based lubricant penetrates down into spaces of one-millionth of an inch to handle the most reluctant seizures.

Assembly Fluids and Lubricants:
Anti-Seize Paste:
xx1) Fastener ANTI-SEIZE PASTE. Yeah, it's smelly and makes a slippery mess on your fingers, but this stuff is a life-saver for any true wrencher, because it prevents problems down the road. Use it on any metal fastener that does not require a "loctite" thread-locker material to be used. This means on just about every fastener that is carb, engine case, or suspension-related! (except for carb upper and lower rack-mount screws and butterfly valve screws, which do require the use of a thread-lock fluid). If you think that it might, sometime, in the future, need to come off: use anti-seize compound! NOTE: the "base" metal material used in the different anti-seize pastes below do not determine what type of fastener to use such pastes on; it merely signifies what base material is used to create the anti-seize paste. You can use any "base-metal" anti-seize paste on any type of fastener and metal.
NOTE: the use of anti-seize compounds will result in a TORQUE-MULTIPLYING EFFECT……..the result of a reduction in friction between the threaded contact points……and thus fasteners treated with anti-seize compound should have their torque values reduced by at least 10-15% when installed into steel material, and up to 25% into aluminum materials or other “soft” metals” (such as spark plugs into cylinder heads, or almost any other type of fastener into the engine) …… note that this rule applies only to service manual torque specifications on fasteners that are not indicated to be treated with anti-seize fluid by the factory …. if the factory manual specifies the use of an anti-seize coating, then the specified torque value for that fitting already takes into account the “reduced torque” necessary.

xx2) The next most important tool: fastener THREAD LOCKER FLUIDS. Use on any fastener that you don't normally ever remove, to make sure that it stays that way. Comes in a variety of formulas, each one designed for a specific use as explained below. NOTE: the damper rod retaining bolt (in the very bottom of the fork tube lower leg, screwing up into the bottom of the damper rod) requires the use of the HCP1267 / HCP27756 medium-strength or the HCP1268 high-strength thread-locking fluid. Yamaha recommend the high-strength fluid, but we’ve found that the medium-strength fluid works as well and makes future dis-assembly a bit easier.

ft4) These stainless-steel, bristle-wire DE-BURRING BRUSHES will work wonders on the upper cap bolt area on both the threaded and the non-threaded style of fork tubes. Tubes that use threaded cap bolt (all XJ650 Turbo, all XJ700 models, XJ750-X models, XJ750 Maxim and Midnight Maxim, XJ900RK, and XJ1100 models) should use the HCP10223 butterfly brush; non-threaded tubes can use either the HCP10222 spiral brush or the HCP10223 butterfly brush. Both style brushes have stems that are designed to be used in a standard power drill, and should be used at 850 rpm's or less. These brushes will make quick and meaningful work of the cleaning and polishing of this critical area on your upper fork tubes.

FORK OIL:
Unlike motor oil or gear oil, fork oil's major purpose is not lubrication.....rather, it acts as part of the suspension system, providing both damping and rebound control functions. The different "weight" or viscosity of fork oils allows you to modify the ride and handling characteristics of your bike in a fairly simple way.
And yes, it IS a lubricant also!
Although many people----including, unbelievably, Yamaha itself----recommends the use of engine motor oil as a substitute for fork oil, this is not a very good idea. Engine oils (or any multi-viscosity oil) uses additives and detergents that, while wonderful in for their intended purposes inside an engine block, tranny case, or rear drive unit, are not such a good idea inside forks. Forks operate at a much lower temperature and temperature RANGE than engine and drivetrains do, and thus do not need all those additives. And fork oil also tends to contain higher percentages of molybdenum disulfide and anti-foaming agents than engine or gear oil, both of which are very important to proper fork operation.
As a small example.......most motor oils are of a multi-viscosity nature (such as 10W30) which change their viscosity in relation to their temperature (thin when cool, thicker as they warm). A very necessary and useful feature for an engine, where you do not want your oil thinning out as the engine warms up. Not such a good idea for your suspension----unless for some reason you WANT your handling characteristics to change (get stiffer) as the forks heat up!
Proper fork oil levels and scheduled change intervals are important for fork performance and fork part longevity.....water contamination, as well as particulate wear will accumulate in fork oil, and since there is no oil filtering mechanism within your forks, the only way to get the grit and gunk out (before it chews up your oil seals and slider bearings!) is to change your fork fluid regularly. Yamaha recommends a fork fluid change every 10,000 miles or 24 months (all models except XJ700's), or every 16,000 miles or 24 months (all XJ700 and XJ750-X models). If you just bought a used bike, we recommend you do a fluid change as soon as possible, because just like other routine maintenance tasks (besides engine oil changes), this is one that has very likely been ignored for the last 10-12 years!
HINT: there’s a puddle of fluid under your wheel, in the area of the brake caliper. Unless the source of the leak is fully obvious, how can you tell if it’s brake fluid of fork oil? Try to mix a few drops of water into the fluid; fork oil (or engine/gear oil) won’t mix and the water will “ball up”; brake fluid will integrate with water and absorb the water.
Fork oil capacities and recommended weights are as follows. The amounts listed are per fork tube:
XJ550 Maxim: 272cc or 9.20 fluid ounces. 10W fork oil.
XJ550 Seca: 230cc or 7.78 fluid ounces. 10W fork oil.
1980-81 XJ650 Maxim and Midnight Maxim: 262cc or 8.86 fluid ounces. 10W fork oil.
1982-84 XJ650 Maxim: 278cc or 9.40 fluid ounces. 10W fork oil.
1982 XJ650RJ Seca: 236cc or 7.98 fluid ounces. 10W fork oil. Fork oil level is specified as 400mm (15.75") below the top of the tube without the spring installed, forks fully collapsed.
1982 XJ650LJ Turbo: 238cc or 8.04 fluid ounces. 10W fork oil. Fork oil level is specified as 180mm (7.09") below the top of the tube without the spring installed, forks fully collapsed.
1983 XJ650LK Turbo: unknown.
1985-86 XJ700 non-X: 383cc or 12.96 fluid ounces. 10W fork oil.
1985-86 XJ700-X: 389cc or 13.16 fluid ounces. 10W fork oil.
1982 XJ750 Maxim: 257cc or 8.69 fluid ounces. 10W fork oil.
1983 XJ750 Maxim and Midnight Maxim: 257cc or 8.69 fluid ounces. 10W fork oil. NOTE: owner's manual states that the fork oil capacity is 278cc (9.40 fluid ounces). It is unknown which measurement is correct.
1981-83 XJ750 Seca: 309cc or 10.45 fluid ounces. 20W fork oil.
1983 XJ750 E-II Seca or 1984 XJ750RL Seca: 286cc or 9.67 fluid ounces. 5W fork oil. Fork oil level is specified as 168mm (6.61") below the top of the tube without the spring installed, forks fully collapsed.
1983 XJ900RK Seca: 286cc or 9.67 fluid ounces. 5W fork oil. Fork oil level is specified as 164mm (6.46") below the top of the tube without the spring installed, forks fully collapsed.
1982-84 XJ1100 Maxim and Midnight Maxim: 210cc or 7.10 fluid ounces. 10W fork oil. Fork oil level is specified as 210mm (8.27") below the top of the tube without the spring installed, forks fully collapsed.
IMPORTANT NOTE: the above fork oil VOLUMES are for use only when using the stock fork springs. The use of aftermarket performance front fork coil springs will change those volumes, since aftermarket springs are thicker than stock----and thus displace more oil. Using the stock oil fluid VOLUME with aftermarket fork springs is a sure way to OVERFILL your forks, with the very real possibility of blowing out fork seals.
Unlike with your engine oil, where a bit too much or too little oil volume in the crankcase is not really a significant concern, with fork oil, too much or too little can cause real problems (too much oil can result in blown oil seals and a stiff, harsh ride, while too little oil volume results in excessive foaming, a soft mushy ride with possible bottoming, and erratic fork performance and lots of front end "dive" upon braking).
A better way to determine the amount of fork oil that is needed and necessary is via the measurement of the fork oil LEVEL within the tubes.....sort of like measuring the oil level with a dipstick. Yamaha does not specify this level for all models; and in any case, if using aftermarket springs, the factory oil level recommendation is not always useful. The maximum oil level should be 5-1/2" (140mm) below the top of the inner fork tube, measured with all internal fork tube components installed EXCEPT FOR THE SPRINGS, and with the inner fork tube fully collapsed into the lower (outer) tube.
In order to be as accurate as possible, we recommend the use of a suitable measuring device, such as the HCP1728 oil level syringe listed further below.
And finally, the fork oil viscosity can be changed from the factory recommendations to give a softer or firmer ride.......the lower the viscosity, the thinner the oil, and the softer the ride (i.e. 5W oil is thinner than 10W which is thinner than 20W, etc.) In this regard, you would certainly be correct in thinking of fork oil as a suspension "tuning tool"! Note that a thicker oil viscosity will have much more effect on the fork "rebound" characteristics than it will on the fork compression dampening function.

ffo3) Red Line Oil products line of SYNTHETIC FORK OILS are some of the best, highest-performance fork oils developed specifically for this purpose. They provide exceptional shear lubrication, are highly resistant to any viscosity changes, and provide excellent seal lubrication as well as very high anti-foaming properties. All of these oils are completely compatible with each other, which means that different weights can safely be mixed with each other to create "custom-weights" of fork oil for the utmost in suspension tuning flexibility. NOTE: oils, if mixed for a different viscosity, should be done in a large enough batch to provide enough oil for both front forks. You do NOT want to be running different oil viscosity's in the left and right fork tubes!
Also, do not mix different brands, styles, or types of oils........you can only safely mix forks oils together from one manufacturer!

Fork Tube Oil Level Gauges:
HCP1728 Fork tube oil fluid level measurement GAUGE AND SYRINGE. This handy tool makes the measurement of the fork oil level easy and accurate. NOTE: the proper amount of fork oil is determined via the measurement of the fork oil LEVEL (distance below the very top of the inner tube) rather than a volume AMOUNT of oil specification. Too little oil will make the ride mushy, while too much oil makes the ride harsh (and can blow out the oil seals!)

ffl4) Aftermarket fork oil measurement GRADUATED CYLINDERS. The best way to measure the precise amount of fork oil fluid is via the use of these lab-quality measurement cylinders. Available in either transparent (clear) or translucent (cloudy) durable plastic construction, they all have easy-to-read scale numerals (milliliters) and feature a "non-wetting" inner surface coating that prevents the concave "meniscus" from forming at the top of the fluid, thus insuring a much more accurate level reading. Large bases insure stability while large spouts make "the pour" easy and prevent messy drips. Very useful device to have for front fork oil changes.

HCP9108 Aftermarket air-assisted forks LOW PRESSURE AIR GAUGE, heavy-duty 0-20 psi pencil (stick) pressure gauge marked in 1/2-psi increments, perfect for checking fork air pressures on models so equipped. Very high quality and much more accurate than standard tire pressure gauges, which is very important on the fork pressures as an imbalance between the fork pressure can lead to steering and stability issues, while too much pressure will blow out the lower tube oil seals!
